Lead Team of Mechanical Engineers analyzing Supersonic (SS) Turbofan engine Bypass Duct (BP) (axi and non-axisymmetric configurations) for flow/pressure losses and integration of engine Accessory Gear Box (AGB) Externals and surrounding aero structures for subsonic and unacceptable SS flow within aggressive and limiting Aircraft (A/C) nacelle envelope and engine thrust shortfall with large diameter fan configuration.Assisted with acoustic analysis of propulsion A/C engine Nozzle configurations to meet next gen commercial CAT+4 engine noise Take Off requirements during Ground Run, Rotation and at 1000 feet of altitude (A/C climb out to 1000 feet). Worked on challenges to Hot Section cooling due to reduced core flow by engine start bleed valves used to dump hot Compressor air into bypass flow at high power setting and extreme BP flow SS choked flow conditions.
